Just days after donning a white dress to show off her 15-carat engagement ring at an event with Kanye West, Kardashian donned her new favorite color again.This time, the reality star rang in her 33rd birthday — again — with a paid appearance at a Tao Las Vegas bash alongside her betrothed.

Kardashian's white lace dress, which showed off her svelte post-baby body, was purchased in Paris while she was pregnant, according to People. (Not a bad gym reward.) And she was already talking about her upcoming wedding.

"We honestly haven't had a moment to talk about it or even breathe, so we haven't really talked about it, but whatever he wants," she told People. Kardashian also said it was a sure thing that Bruce Jenner would be walking her down the aisle. (No comment, apparently, on why he was not invited to the proposal.)

There may be another reason West was grinning at the party. Kardashian told the magazine her elaborate engagement at AT&T Park was an "absolute, complete surprise." It seems her entire family assumed it was a surprise birthday. "I was shaking so much, shaking the entire time," she said. "Like, 'Is this really happening?' It was like an out-of-body experience."
